To what volume in millimeters must 50.0 ml of 18.0 m h2so4 be diluted to obtain 4.35 m h2so4?

We know that to relate solutions of with the factors of molarity and volume, we can use the equation: 

**NOTE: The volume as indicated in this question is defined in L, not mL, so that conversion must be made. However it is 1000 mL = 1 L.

So now we can assign values to these variables. Let us say that the 18 M  is the left side of the equation. Then we have:



We can then solve for :

and  or 

We now know that the total amount of volume of the 4.35 M solution will be 210 mL. This is assuming that the entirety of the 50 mL of 18 M is used and the rest (160 mL) of water is then added.
